3. Select proper thickness of shim based on the backlash
measured with dial gauge and on the table shown.
1.Values in this table indicate dial gauge readings
that are obtained when using special tool.
2.Measure backlash several times while changing
gear teeth contact position.
4. After the adjustment, remove backlash measuring tool, and
turn drive shaft while pulling it up to see if it turns smoothly.
If not, reduce shim thickness 0.05mm and adjust backlash
again.
If engagement of bevel (A) gear with pinion (B) gear
is imperfect, they may produce abnormal noise
when turning drive shaft while pulling it up. In such
case, reduce shim thickness 0.05mm.
Keep the following matters in mind when
performing the measurement.
· Shaft 1 that secures forward (A) gear has
been tightened so that drive shaft 9 cannot be
turned over backlash if it is turned lightly.
· Fixing of drive shaft bearing q is performed
only with pump case (lower) 6. Clamp 5
should be attached as close to pump case
(lower) 6 as possible.
· When performing the measurement by using
dial gauge, gear case and dial gauge are fixed
and drive shaft 9 is turned while it is pulled
up. During the measurement, be sure that
other parts do not produce play (play of drive
shaft 9 itself and the one between drive shaft
9 and bearing).
